I’m hesitant to compliment her on her bravery and knowledge of body language, for the sole reason that she should not be interacting with the cheetahs at all. Considering how they reacted to her, this was probably the first time they’d ever seen her, but if she came back repeatedly, they’d get used to her- and wild animals should never, ever think they are safe around humans.
